swEOS: salt- water (NaCl-H2O) Equation of State

What it is:	An extensible code written in C++ to support research in using EOS and thermodynamic properties of H2O-NaCl system in both p-T-X and p-H-X coordinate space.
Motivation:	To provide easy-to-use application, library and API for cross-platforms and programing languages. The users can implement their own research calculation using the library and APIs.
